Assignment VIII: Deep Learning

Question 1

Use the dataset, DEMO_DATA/chinese_name_gender.txt and create a Chinese name gender classifier using the deep learning method. You need to include a few important considerations in the creation of the deep learning classifer.

1. Please consult the lecture notes and experiment with different architectures of neural networks. In particular, please try combinations of the following types of network layers:

   • dense layer

   • embedding layer

   • RNN layer

   • bidirectional layer

2. Please include regularizations and dropbouts to avoid the issue of overfitting.

3. Please demonstrate how you find the optimal hyperparameters for the neural network using keras-tuner.

4. Please perform post-hoc analyses on a few cases using LIME for more interpretive results.
